SBEGIFIGATION forming part of LettersPatentNo. 515,208, dated February20,1894.

Application filed October 2, 1893. Serial No. 486.977. (N model.)

To aZZ whom it may concern:

Be it known that we, JOSEPH A. GLEIXNER, a resident of Fairhaven, andPETER SCHAFF, a resident of Baldwin township, county of Allegheny, Stateof Pennsylvania, have invented a new and useful Improvement inSeed-Sowers; and we do hereby declare the following to be a full, clear,and exact description thereof.

. Our invention relates to seed sowers, such [0 as set forth in LettersPatent of the United States granted to us May 2, 1893, No. 496,515.

Our invention comprises certain improvements hereinafter clearly setforth.

To enable others skilled in the art to make I 5 and use our invention,we will describe the same more fully, referring to the accompanyingdrawings, in which- Figure 1 is a side View of our improved seed sower.Fig. 2 is a top view. Fig. 3 is an enlarged plan view of the seedcylinder and its accompanying parts. Fig.4t is an enlarged cross sectionof the seed cylinder. Fig. 5 is an enlarged View of the releasingdevice. Fig. 6 is an enlarged View of the segmental bearing whichcarries the axle. Fig 7 is a perspective view of a portion of thecylinder shogving the pocket opened to discharge the see Like lettersand numerals of reference in- 0 dicate like parts in each of thefigures.

The frame of the seed sower is composed of the bed a, the inclined barsa suitably braced by rods a and a The upper ends of said inclined bars aare curved to form handles a Secured to the forward end of the bed a arethe segmental bearings b. In describing the construction of thesesegmental bearings we will use the singular number. The segmentalbearing 1) is formed in two parts in order to provide for the adjustmentoft-he journal box 0 at different heights therein. The two parts of thebearing arejoined at their lower ends by the pivotal joint b which actsin the 4 5 nature of a hinge, so that when the upper ends are free thetwo parts of the bearing'may be separated to provide for'the adjustmentof the journal box therein. The upper ends of the bearings b areconnected'by the bolt and nut 19?, all of which is clearly shown in Fig.t upon the revolution of the cylinder h, where- 10::

6. Furthermore, one of the parts of the segmental bearing 1) is providedwith the serrated face 5 The journal box 0 is provided with the recesses0' within which the inner faces of the segmental bearing b fit, wherebysaid box is firmly held within said bearing. To add to the security ofthe box 0 one of the recesses of said box has formed therein the tooth 0adapted to engage with the serrated face b of the bearing 1). Thejournal boxes 0 support the axle d and secured to said axle is the wheel6. One end of said axle has secured thereto the sprocket wheels (1'. Asprocket chain f connects the sprocket wheels d with similar wheels 9 onthe shaft 9 which carries the seed cylinder h. The shaft 9 is journaledin suitable bearings g on the bed a, and secured to said shaft is theseed cylinder h. The seed cylinderh may be divided into compartments h,as shown in dotted linesin Fig. 3, in order that diiferent kinds ofseeds may be sown at the same time. Access to each compartment is had bymeansof the openings '5 formed in the walls of said cylinder, saidopenings being provided with the sliding covers 1''. Through theopeningsil the seeds may be fed to the different compartments h. Theseed cylinder h is furthermore providedwith the openings is arranged inseries extending across the cylinder, said'series being arranged atsuitable intervals around the circumference of said cylinder, and theopenings in one series following in line with those of the precedingseries. The openings 70 lead into the different compartments of thecylinder it.

Each series of openings 70 is provided with a corresponding number ofpockets Z. These pockets Z are mounted on a common bar Z,

said bar having'journals Z on the ends the re-.

of journaled in suitable bearings Z in the flanges h of the cylinder h.In order to retain the pockets Z normally in such position as to closethe openings 76 we provideaspring m, said spring being secured to thebarl and encircling the journal Z with the free end thereof in contactwith the cylinder h.

Projecting from one end of the bar Zis the arm 0 adapted to be engagedby a finger p upon the pockets Z will discharge the seed to the drills,as will be more fully hereinafter set forth. This fingerp extends outfroma slotted arm 19' which is secured to the segm e11- tal arm q, athumb nut q engagingwith said slotted arm 19' and with a slot g in saidsegmental arm q. By this construction the fingerp may be raised orlowered or shifted to the right or left according as the thumb nut g,which holds said finger in position, is moved to the right or leftWithin the slot g in the segmental arm q. A bolt or pin 9" passesthrough the lower end of the segmental arm q, said bolt or pin beingjournaled in bearings r on the bed a. A suitable spring 8 encircling thebolt 01'' pin 7' acts to retain the segmental arm q in an uprightposition and the finger 19, carried thereby, in such proximity to thecylinder it that upon the revolution of said cylinder the finger p willbe in the path of the arm 0, whereupon said arm 0 will be forced backuntil the finger p has been passed, when said arm 0 will resume itsformer position. The segmental arm q has an outwardly projecting tonguetto which is secured the rod t, said rod extending up and secured to thelever u pivoted at u to one of the inclined bars a of the frame. Bymeans of this construction the operator, by raising the lever to, drawsdown the segmental arm g, and at the same time the finger p out of thepath of the arm 0 on the revolving cylinder It. Back of the cylinder h,and secured to the bed a, is the chute Q), said chute having thepartitions a) therein which form a series of small chutes 1, 2, 3, 4,850. These chutes l, 2, 3, &c., register at theirlower ends with theinlets of the seed drills 10, each chute leading down to its particulardrill. The said chute i; may be arranged to slide in suitable guides 41secured to the bed at. These drills are of the ordinary construction andmay be secured in place on the bed a in any convenient manner. 7,

A marker, such as shown in the Letters Patent above referred to, may beused in connection with the present invention.

The rear roller :12 may be adjusted at different heights to correspondwith the height to which the front wheel e is adjusted, the purpose ofsaid roller as being to roll over the ground traversed by the drills andcover the seed expelled therefrom.

The operation of our improved seed sower is as follows:-The wheel e andrear roller m having been adjusted at the proper height relative to thedepth at which it is desired to sow the seed, and the seed, all of onekind or of different kinds as the case may be, having been introducedinto the cylinder h by means of the openings 1', the sower is then readyfor sowing. As the operator pushes the sower over the soil the cylinderh, through the axle d, sprocket wheels (1, chain f and sprocket wheels9', is caused to rotate in the direction of the arrow. It is apparentthat upon the ascent of the cylinder the pockets Z will be filled'withseed, that is, the pockets on that portion of said cylinder from thepoint where the cylinder beginsits ascent to a point just beyond thechute 7) where the pockets begin to empty the seed back into thecylinder. The ascent of the cylinder h brings the arm 0 into contactwith the finger p, whereupon the said arm 0 is forced back, causing thebar Z to turn slightlyin its bearings and allow the pocketsZto delivertheir contents into their respective chutes l, 2, 3, 4, 5. The arm 0having passed over the finger p will be forced back to its normalposition by means of the spring on and the pockets Z will likewiseresume their normal position over the openings k. The seed delivered tothe chutes l, 2, 3, &c., by the pockets Z will pass down and out theseed drills to into the soil. W'hen itisnot desired to empty the pocketsZ into the chutes, such as in transporting the sower to and from theplace Where the sowing is to be done, the operator by grasping the leverto and raising the same throws the fingerp away from the cylinder andout of the path of the arm 0.

In some cases it is desirable to sow more seed than in others, accordingto the kind of seed, and for this reason the arm pwith the fingerp canbe adjusted at different heights or at different angles with referenceto the segmental arm g. It is apparent that the lower the position ofsaid finger p the sooner the arm 0 will come in contact with said fingerand the entire contents of the pockets will be discharged into thechutes. It is further apparent that if the finger p is adjusted in suchposition as to strike the arm 0 near the inner end .of said arm, thepockets will be opened to their full extent and for a greater length oftime than where said finger strikes the outer end of said arm 0. In thelatter case the pockets will only be partially opened and that for ashort time whereby only a portion of the seed held therein will escape.This adjustment is also of great advantage in sowing seed of differentsizes, as in the case of large seed it is desirable to open the pocketsto the full extent.
